Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and more specifically, to a performance testing device. Background Technology

[0002] Currently, in the maintenance and optimization of power transmission mechanisms (such as gear transmission mechanisms), lubricating grease, as a key lubricating medium, directly affects the operating efficiency and lifespan of mechanical equipment due to its performance and lifespan. However, the service life of gears and lubricating grease is affected by a variety of factors, including but not limited to mechanical stress, air pressure, wind speed, temperature, and load conditions. These factors can lead to oxidation, wear, and electrolytic corrosion of the lubricating grease, thereby accelerating the failure rate of the moving mechanism.

[0003] In existing technologies, the lifespan of lubricating grease can be assessed through actual machine operation tests, observing the grease's performance under real-world conditions. While this provides a more accurate reflection of the grease's lifespan under actual conditions, it often requires starting the corresponding operational machine before testing the grease's performance. This makes it inconvenient to test the grease before actual operation and also hinders the timely acquisition of the grease's performance parameters under different operating conditions.

[0061] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0062] like Figures 1 to 8As shown, an embodiment of this utility model provides a performance testing device for testing the performance of a rotating component 100 under test and / or the performance of a lubricating grease. The performance testing device includes a first rotating shaft 1, a first driving component 2, and a torque detection component 3. The first rotating shaft 1 is rotatably disposed, and the rotating component 100 under test is sleeved on the outer periphery of the first rotating shaft 1. The first driving component 2 meshes with the rotating component 100 under test, and at least one of the rotating component 100 under test and the first driving component 2 is coated with lubricating grease. The torque detection component 3 includes a torque detection element 31 and a clamping structure 32 connected to each other. The torque detection element 31 is used to detect the torque of the first rotating shaft 1. The torque detection component 3 is movably disposed beside the first rotating shaft 1 to move to a clamping position and a releasing position. When the torque detection component 3 is in the clamping position, the clamping structure 32 clamps the first rotating shaft 1. When the torque detection component 3 is in the releasing position, the clamping structure 32 releases the first rotating shaft 1.

[0063] For example, torque detection element 31 is a torque sensor.

[0064] The first driving component 2 meshes with the rotating component 100 under test. Driven by the first driving component 2, the operating state of the rotating component under actual working conditions can be simulated. By adjusting the rotational speed of the rotating component 100 under test, the lifespan and reliability of the rotating component 100 under different speed conditions can be simulated. By coating at least one of the first driving component 2 and the rotating component 100 under test with grease, the testing device can directly evaluate the performance of the grease under actual working conditions, including its lifespan, wear resistance, and stability. The torque detection component 3 includes a torque detection element 31 and a clamping structure 32. The torque detection component 3 can move between the clamping position and the releasing position according to test requirements, ensuring the alignment of the torque detection component 3 with the first rotating shaft 1, thus ensuring the accuracy and reliability of the test data. The performance testing device provides an efficient and accurate evaluation of the performance of the rotating component 100 and the grease under test by directly measuring the torque change of the first rotating shaft 1 and judging the performance of the rotating component 100 or the grease based on the torque change of the first rotating shaft 1, thus shortening the test cycle.

[0065] In one embodiment, the rotating component 100 under test is a gear under test, and the first driving component 2 is a driving gear. This performance testing device drives the gear under test via the driving gear, enabling it to test the performance of the gear under test and to apply grease to at least one of the gear under test and the driving gear to test the performance of the grease.

[0066] In another embodiment, the rotating component 100 under test is a worm gear under test, and the first driving component 2 is a driving worm. This performance testing device can drive the worm gear under test via a driving screw, mimicking the application scenario of the worm gear under test, to test its performance, and to apply grease to at least one of the worm gear under test and the driving screw to test the performance of the grease.

[0067] The following explanation uses the rotating component 100 to be tested as the gear to be tested and the first driving component 2 as the driving gear as an example.

[0068] like Figure 1 and Figure 2 As shown, a performance testing device is used to test the performance of a rotating component 100 under test and / or the performance of a lubricating grease. The performance testing device includes a first rotating shaft 1, a first driving component 2, and a torque detection assembly 3. The first rotating shaft 1 is rotatably mounted, and the rotating component 100 under test is sleeved on the outer periphery of the first rotating shaft 1. The first driving component 2 meshes with the rotating component 100 under test. The performance testing device also includes a second rotating shaft 22, with the first driving component 2 sleeved outside the second rotating shaft. One end of the first driving component 2 is connected to a torque detection assembly 3. A driving device 21 is provided, wherein at least one of the rotating component 100 to be tested and the first driving component 2 is coated with grease. Specifically, after the first driving device 21 is started, it drives the second rotating shaft 22 and the first driving component 2 to rotate simultaneously, thereby causing the rotating component 100 to be tested, which meshes with the first driving component 2, to rotate. Through the drive of the first driving component 2, the rotating component 100 to be tested can rotate at different speeds to simulate the operating state of the rotating component 100 to be tested under different actual working conditions, so as to test the life and reliability of the rotating component 100 and / or the grease.

[0069] For example, the first driving device 21 is a motor.

[0070] Specifically, the first rotating shaft 1 is vertically arranged, and the performance testing device further includes a force loading member 4. The force-applying end of the force loading member 4 acts on the end face of the rotating component 100 under test, and the loading force of the force loading member 4 can be adjusted. In this embodiment, the first rotating shaft 1 is vertically arranged, and the first rotating shaft 1 and the rotating component 100 under test are subjected to the forces of gravity and the force loading member 4. The force-applying end of the force loading member 4 can directly act on the end face of the rotating component 100 under test under the action of gravity, without the need for a complex loading system as required by a horizontally arranged first rotating shaft 1. Furthermore, this embodiment can accurately apply the required loading force to simulate the stress changes of lubricating grease under actual working conditions, ensuring the accuracy and reliability of the test results.

[0071] For example, the force loading element 4 includes at least one weight, and the load applied to the end face of the gear under test is adjusted by adjusting the number of weights.

[0072] Furthermore, the performance testing device includes a torque detection component 3, which comprises a torque detection element 31 and a clamping structure 32 connected to each other. The torque detection element 31 is used to detect the torque of the first rotating shaft 1. The torque detection component 3 is movably disposed beside the first rotating shaft 1 to move to a clamping position and a released position. When the torque detection component 3 is in the clamping position, the clamping structure 32 clamps the first rotating shaft 1; when the torque detection component 3 is in the released position, the clamping structure 32 releases the first rotating shaft 1. The torque detection component 3 can move between the clamping position and the released position according to the testing requirements, ensuring the alignment of the torque detection element 31 with the first rotating shaft 1, and ensuring the accuracy and reliability of the test data. The performance testing device provides an efficient and accurate evaluation of the performance of the rotating component 100 under test and the lubricating grease by directly measuring the torque change of the first rotating shaft 1.

[0073] Furthermore, the performance testing device includes a controller 10, which is connected to the torque detection element 31 via a signal. It can monitor and record torque change data in real time. Through data analysis, the performance degradation and lifespan of the grease under specific working conditions can be intuitively evaluated, providing a basis for the selection and optimization of the grease.

[0074] Furthermore, the testing device includes a testing platform 7, a protective cover 8, and a heater 9. The protective cover 8 is disposed on the testing platform 7, and contains at least a portion of the heater 9, the rotating component 100 under test, the first driving component 2, and the first rotating shaft 1. One end of the first rotating shaft 1 extends out of the protective cover 8. The protective cover 8, situated on the testing platform 7, forms a closed testing environment. The heater 9, the rotating component 100 under test, the first driving component 2, and a portion of the first rotating shaft 1 are housed within the protective cover 8, while one end of the first rotating shaft 1 extends outside the protective cover 8. The heater 9 simulates temperature changes in the actual working environment, making the performance evaluation of the rotating component 100 under test and the lubricating grease more realistic and ensuring precise control of the temperature conditions of the rotating component 100 under test during the test. The protective cover 8 not only provides safety isolation, avoiding external interference, but also works in conjunction with the heater 9 to maintain a constant temperature in the testing environment, making the entire testing process more accurate and controllable. One end of the first rotating shaft 1 extends out of the protective cover 8, facilitating connection to external measuring equipment such as the torque detection element 31. This allows for monitoring of the torque changes of the rotating component 100 under different test conditions, thereby determining the performance changes and ultimate lifespan of both the rotating component 100 and the lubricating grease, and improving testing efficiency and accuracy. This structural design and operating method effectively reduces the testing cycle while ensuring the reliability of test results, providing an efficient and accurate method for the screening and evaluation of lubricating grease.

[0075] Furthermore, the protective cover 8 includes a first cover 81 and a second cover 82 that interlock, and the first cover 81 and the second cover 82 are detachably connected. This not only facilitates the maintenance and replacement of the internal structure of the protective cover 8, but also provides effective heat insulation and protection during the experiment, avoiding interference from the external environment on the test results. At the same time, this structural design also facilitates pre-experiment preparation and post-experiment cleaning, ensuring environmental consistency for each experiment, thereby improving the accuracy and reliability of the grease life test. For example, the connection method of the first cover 81 and the second cover 82 can be selected according to actual needs, such as using a snap-fit ​​83 or magnetic connection.

[0076] Furthermore, such as Figure 1 , Figure 3 and Figure 4 As shown, the performance testing device includes a position adjustment component 5, on which the torque detection component 3 is mounted. This position adjustment component 5 moves the torque detection component 3 in three directions: X-axis, Y-axis, and Z-axis. The X-axis, Y-axis, and Z-axis are mutually perpendicular, and the extension direction of the Z-axis is parallel to the first rotating shaft 1. The position adjustment component 5 can move precisely in the X, Y, and Z-axis directions, allowing the torque detection component 3 to be accurately positioned above the first rotating shaft 1, ensuring good alignment between the torque detection component 3 and the first rotating shaft 1. This three-axis adjustment capability not only improves the flexibility of the test but also ensures accurate life assessment of the grease and the rotating component 100 under various operating conditions, such as different temperatures, speeds, and loads. By monitoring the torque changes of the rotating component 100 under continuous rotation under multiple operating conditions, the performance degradation of the grease and the wear of the rotating component 100 can be directly reflected, thereby quickly assessing the life of the grease and its impact on the performance of the rotating component 100. Compared to traditional indirect calculation, this direct measurement method is simpler to operate, yields more reliable results, and avoids response delays and accuracy losses caused by system coupling.

[0077] Specifically, the testing device includes a base 6, and the position adjustment component 5 includes an X-axis linear motion part 51, a Y-axis linear motion part 52, and a Z-axis linear motion part 53. The Z-axis linear motion part 53 is disposed on the base 6, the Y-axis linear motion part 52 is disposed on the Z-axis linear motion part 53, the X-axis linear motion part 51 is disposed on the Y-axis linear motion part 52, and the torque detection component 31 is disposed on the X-axis linear motion part 51. The Z-axis linear motion part includes a bracket 531, a lead screw 532, a guide rod 533, a mounting base 534, and a second drive device 537. The second drive device 537 is disposed on the base 6 and is connected to the lead screw 532. The lead screw 532 is rotatably disposed on the bracket 531. The guide rod 533 is mounted on the bracket 531 and spaced apart from the lead screw 532. The mounting base 534 is slidably disposed on the lead screw 532 and the guide rod 533. The X-axis linear motion unit 51, Y-axis linear motion unit 52, and Z-axis linear motion unit 53 are arranged in a stacked manner, with the torque detection element 31 mounted on the X-axis linear motion unit 51. Specifically, the Z-axis linear motion unit adopts a design combining a bracket 531 and a lead screw 532. The lead screw 532 can rotate relative to the bracket 531 and is equipped with a guide rod 533, which is parallel to the lead screw 532 and fixed to the bracket 531, ensuring that the mounting base 534 moves smoothly along the lead screw 532 while remaining stable on the guide rod 533. This design allows the torque detection element 31 to be accurately positioned in three degrees of freedom.

[0078] The Y-axis linear motion unit 52 includes a Y-axis drive device 521 and a first ball screw structure 522, which are connected in a transmission manner. At least a portion of the first ball screw structure 522 is connected to the base plate 523. The X-axis linear motion unit 51 is disposed on the base plate 523. The X-axis linear motion unit 51 includes an X-axis drive device 511 and a second ball screw structure 512, which are connected in a transmission manner. At least a portion of the second ball screw structure 512 is connected to the torque detection component 3. The extension directions of the first ball screw structure 522 and the second ball screw structure 512 are perpendicular to each other. The first ball screw structure 522 and the second ball screw structure 512 have the same structure, both including a screw, a nut and balls disposed between the screw and the nut. In the Y-axis linear motion part, the rotation of its corresponding screw causes the nut to move along the screw, thereby driving the base plate to move along the Y-axis. In the X-axis linear motion part, the rotation of its corresponding screw causes the nut to move along the screw, thereby driving the torque detection component 3 to move along the X-axis.

[0079] Furthermore, the test platform 7 and the support 531 are mounted on the base 6, and a shock-absorbing structure 535 is provided between the base 6 and the support 531. The design of the base 6 enhances the stability and seismic resistance of the overall structure. By configuring the shock-absorbing structure 535 between the base 6 and the support 531, the impact of external vibrations on the test process is effectively absorbed and reduced, ensuring the accuracy and reliability of the test results.

[0080] Furthermore, at least one end of the bracket 531 along the Z-axis is provided with a limiting structure 536, which is used to limit and abut against the torque detection component 3 to restrict the movement of the torque detection component 3. This prevents equipment damage caused by excessive movement of the position adjustment component 5, thereby improving the safety and ease of operation of the device.

[0081] Furthermore, such as Figures 5 to 7 As shown, the clamping structure 32 of the torque detection component 3 includes a support 321, a second drive member 322, a transmission component 323, and at least two grippers 324. The torque detection component 31 is mounted on one end of the support 321. The support 321 has a receiving space 3211 and a first mounting groove 3212 communicating with and penetrating the wall thickness direction of the support 321. The second drive member 322 is mounted in the first mounting groove 3212. The transmission component 323 is mounted within the receiving space 3211, and the second drive member 322 is connected to the transmission input end of the transmission component 323. Each gripper 324 is connected to the transmission output end of the transmission component 323, and the gripping end of each gripper 324 extends outside the receiving space 3211. The clamping structure 32 is designed to achieve precise and stable clamping of the rotating component 100 under test, ensuring the accuracy of grease life or rotating component 100 life testing. The support 321 serves as a basic component, with a torque detection element 31 mounted on one end. It has a receiving space 3211 and a first mounting groove 3212 penetrating the wall thickness for mounting a second drive element 322 and a transmission assembly 323. The second drive element 322 is connected to the transmission input end of the transmission assembly 323 at the first mounting groove 3212, and adjusts the movement of the grippers 324 by driving the transmission assembly 323. At least two grippers 324 are connected to the transmission output end of the transmission assembly 323, with their gripping ends extending outside the receiving space 3211, effectively clamping the first rotating shaft 1 after it is inserted. When the second drive element 322 is activated, the transmission action of the transmission assembly 323 causes at least two grippers 324 to move synchronously, clamping the test gear and ensuring good alignment and stability between the test gear and the torque detection element 31.

[0082] For example, the second drive element 322 is a drive handwheel.

[0083] Further, the transmission assembly 323 includes a push rod 3231 and a connecting rod 3232. The push rod 3231 is movably disposed within the receiving space 3211; both ends of the connecting rod 3232 are rotatably connected to the gripper 324 and the push rod 3231, respectively. The push rod 3231 of the transmission assembly 323 is movably disposed within the receiving space 3211, and both ends of the connecting rod 3232 are rotatably connected to the gripper 324 and the push rod 3231, respectively. This allows the gripper 324 to undergo precise displacement adjustment under the action of the push rod 3231. Furthermore, a spring is provided on the outer periphery of the connecting rod 3232 to ensure the operational stability of the multiple grippers 324 during opening and closing.

[0084] The support 321 and the push rod 3231 each have a recessed portion, and the protrusion and the recessed portion cooperate with each other. This cooperation between the protrusion and the recessed portion serves a guiding function, ensuring that the position of the push rod 3231 does not shift radially during the test, thus guaranteeing the accuracy of the torque measurement.

[0085] Furthermore, the support 321 has a connecting shaft at one end facing the torque detection element 31. The extended shaft of the torque detection element 31 and the connecting shaft are connected by a coupling (e.g., a diaphragm coupling), and the torque is calculated by the generated minute deformation.

[0086] The following describes the performance testing process for lubricating grease:

[0087] When using the performance testing device of this application to evaluate the life of lubricating grease, firstly, the lubricating grease to be tested is evenly applied to the surface of the gear to be tested. Then, the gear to be tested is mounted on the first rotating shaft 1, ensuring that the gear to be tested and the drive gear are correctly meshed. Next, the load applied to the gear to be tested is adjusted by adjusting the number of weights. The heating temperature, the rotation speed of the first rotating shaft 1, and other operating parameters are set by the controller 10. The heater 9 is started to preheat to the required temperature, providing a stable testing environment for the lubricating grease. After the test begins, the first drive device 21 drives the second rotating shaft 22 and the first drive component 2 to rotate, transmitting torque to the gear to be tested, so that the gear to be tested continues to operate under preset operating conditions. During this period, the torque detection component 3 is precisely moved to the clamping position in the X, Y, and Z axes by the position adjustment component 5. The jaws 324 of the clamping structure 32, under the control of the transmission component 323, synchronously clamp the first rotating shaft 1. At this time, the torque detection component 31 begins to detect the torque applied to the first rotating shaft 1, records the torque data, and transmits it to the controller 10 for analysis via the data acquisition card. The controller 10 simultaneously receives the rotational speed information of the first rotating shaft 1. After torque detection is complete, the torque detection component 3 moves to the release position, and the gripper 324 releases, allowing the first rotating shaft 1 and the gear under test to continue undisturbed rotation. During the test, the force loading component 4 applies adjustable pressure to the end face of the gear under test according to a preset loading force, simulating load conditions under different working conditions. Throughout the test cycle, the torque detection component 3 periodically performs clamping and releasing actions, continuously monitoring torque changes until the grease or the gear under test shows significant performance degradation or reaches its lifespan limit. The torque detection component 3 transmits the torque signal to the data acquisition card for data recording and simultaneously displays it on the display screen of the torque detection component, obtaining the torque value of the gear under test at the corresponding rotation angle. By analyzing the torque change curve, noise, power, and wear conditions, the final grease life assessment result is obtained, providing a basis for grease selection and performance optimization.

[0088] After the initial test, a new round of operating condition tests can be conducted by changing different types of grease or the gear being tested to evaluate the grease's performance across the entire range. This method of directly measuring torque, compared to indirect calculation, improves operational convenience and the reliability of test results, providing a more scientific and efficient method for grease life assessment.

[0089] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0090] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0091] In the description of this application, it should be understood that the orientation or state relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or state relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0092] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial relationship between a device or feature as shown in the figures and other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0093] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0094] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
